Abstract

Titre : Réacteur et Procédé de sécurité pour réacteur en cas de fusion du cœur La présente invention concerne un procédé de sécurité pour réacteur (1), le réacteur (1) comprenant au moins un circuit primaire (100) et un circuit secondaire (200) fluidiquement isolé du circuit primaire (100), et comprenant au moins un générateur de vapeur (210). En cas de fusion du cœur (30) du réacteur (1) avec formation d’un bain (71) de corium (70) dans un fond (12) de la cuve (10) et formation d’une couche (72) métallique liquide à la surface du bain (71) de corium (70) : le procédé une rupture par explosion de l’isolation fluidique pour mettre en communication fluidique le circuit secondaire (200) avec le circuit primaire (100) de sorte que le fluide secondaire emprunte le circuit primaire (100) pour s’écouler à l’intérieur de la cuve (10) sur ladite couche (72) métallique liquide du bain (71) de corium (70). Figure pour l’abrégé : Fig.5BTitle: Reactor and safety process for reactor in the event of core meltdown The present invention relates to a safety process for reactor (1), the reactor (1) comprising at least a primary circuit (100) and a secondary circuit (200) fluidically isolated from the primary circuit (100), and comprising at least one steam generator (210). In the event of meltdown of the core (30) of the reactor (1) with formation of a bath (71) of corium (70) in a bottom (12) of the vessel (10) and formation of a layer (72) of metallic liquid on the surface of the bath (71) of corium (70): the process a rupture by explosion of the fluidic insulation to put the secondary circuit (200) in fluidic communication with the primary circuit (100) so that the secondary fluid borrows the primary circuit (100) to flow inside the vessel (10) on said liquid metallic layer (72) of the pool (71) of corium (70).
